#745: Accelerating Cloud Migration: How Occidental Petroleum Transformed with Terraform and AFT

November 10, 2025·20 min·2 clips

One team literally requested 10 AWS accounts in a single day and got them.

Episode 745 is a hands-on migration story. Lish introduces Brian Moore from Oxy and Chris Spitzenberger from AWS, then keeps the discussion on how Oxy sped up cloud adoption without making it sound tidy. The mechanics get real attention. The excerpt walks through Terraform, CodeBuild handoffs, provider configuration changes, and the account definitions behind automated provisioning. Brian keeps the examples close to the work. A data mesh team could ask for around 10 AWS accounts for dev, stage, and production, and Oxy could turn those around with Terraform-driven setup and a bit of code generation. Speed matters, but the stronger point is flexibility. The team had to change course when early assumptions turned out incomplete or too expensive. The VPC endpoint example gives the segment some bite. Oxy started with decentralized endpoints in individual accounts, then shifted toward a centralized architecture so it was not paying for unused endpoints everywhere. That meant more cleanup: a new account pattern had to be pushed across roughly 150 accounts at that point. Lish also pulls out the day-to-day value. Teams were not waiting on account creation as the blocker. Chris says Oxy went from zero to more than 100 accounts, and Brian updates the scale to more than 300. The tone stays useful. The close does not pretend migration is smooth; it shows automation helping because plans change, fixes happen, and teams still have to adjust.
